President Donald Trump is preparing to release a list of an additional $200 billion in Chinese products to be hit with tariffs, according to two people familiar with the matter. The Trump administration on July 6 imposed 25 percent duties on $34 billion in Chinese imports, the first time the president has implemented tariffs directly on Beijing after threatening to do so for months. China immediately retaliated with duties on the same value of U.S. goods, including soybeans and cars. The new list would mark the latest escalation of the trade war between the world’s two biggest economies. Financial markets have so far shrugged off the first round of tariffs, which were long-telegraphed, with U.S. stocks up since Friday.
